YORK, ASSIGNOR TO SYRACUSE WASHING MA- NEW YORK, A CORPORATION OF DELAWARE e momia Application filed January 3, 1930. Serial No. 418,237.

This invention relates to a new and improved ironing machine.

v My inventionis particularly well adapted for use in homes and it is designed with the particular purpose of providing an ironing machine which will be easy to operate and which will be so constructed ythat the manipulationvof the various parts thereof may be 'accomplished easily and quickly by the operator.

Themain object of my invention is to provide an ironing machine which will embody all ofthe advantages of large and cumbersome machines but which, itself, is comparatively light and compact so that it may be transported from place to place with the minimum ofeffort.

Another object is to provide an ironing machine which is so constructed that the different types of ironing applicable for different types of material may be accomplished with the minimum amount of manipulation of the different controls of the machine.

Another object is to provide an ironing machine in which the rotation of the ironing roll will be automatically stopped when the1 ironing shoe is moved away from the rol Another object is to provide a means whereby the ironing shoe may be manually moved away from the ironing roll during the operation of the machine. t

Another object is to provide a machine in which the operation of the ironing shoe will be automatically resumed after any manual movement of the shoe from the roll.

Another object is to provide a machine in which the rotation of the ironing roll may bev manually stopped without interrupting the operation of the ironing shoe.

Another object is to provide a means whereby Y the operation of the ironing shoe may be electrically controlled.

Other .objects and advantages relate to the size` shape and relation of parts, all as will more fully appear from the following de,- scription taken in' connection with the accompanying drawings in whichz- Figure 1 is a top plan view of my improved ironing machine.

Referring to Figures 1 and 2, my ironing machine comprises a gear casing 1 havingl adjacent its upper end a laterally extending .tubular boss 2 and having adjacent its lower end a second laterally extending tubularboss 3.

A supporting tube 4 has one end rigidly secured in boss 2 with its outer end extending laterally therefrom. A shaft 5 has its inner end journaled in a ball bearing 6 secured in -the inner end of boss 2 and has its outer end journaledin a ball bearing 7 secured in the outer end of supporting tube 4.

Shaft 5 extends outwardly through and beyond the outer-end of tube 4. v-

A tubular ironing roll 8 has secured in its inner end, as perhaps may best be seen from y Figure 6, an annular collar 9 braced in' pothrough which shaft 5 extends to which shaft 5 is secured as by 'a key 16 for simultaneousA yrotary motion.

The outer end'of shaft 5 extends through plate 13 and is threaded to coact with a nut 17 to secure roll 8 against axial displacement in relationl to shaft f.

JReferring to Figures 2, 6 and 13, a tubular support 18 has one end rigidly securedr in boss3 and has its other end secured in a support or. saddle 19, the lower end ofsaddle 19 being in the same plane as the bottom of .casing 1.

Saddle 19 primarilyl functions as-a bearing l lsupport for shaft 86 (hereinafter to be devbeyond the inner end of boss end of shaft 20 is journaled in scribed) and, altho it is here shown as also functioning as a support'for the ironer shoe 33 and its operating mechanism, such additional support for the shoe 33 is not necessary altho desirable.

A shaft 2O extends through tube 18 and has its inner end journaled in a ball bearing 21 vsecured'in the inner end of boss 3.y

The inner end of shaft 20 extends inwardly 3. The outer a ball bearing 22 secured in the outer end of tube 18.

The outer end of shaft 20 extends outwardly beyond the outer end of tube 18 for connection ywith the ironer'shoe support in a manner about to be described. Although the ironer shoe may besupported 1n a variety of ways, I prefer to support the same in a new and improved way which way has been disclosed and claimed by me in a co-pending application for ironer shoe support filed by me October 18, 1929, Serial No.

This manner of supporting the ironing shoe may best' be seen Figure 12.

I secure to the outer end of shaft 20 as by a key 23 and a set screw 24 a yoke 25. Yoke 25 has at the rear thereof ofa recess 26 having an internal shoulder 27.

0n the upper end of yoke 25 and between the opposite sides thereof is pivotally mounted a rock arm 28 as by a pivot pin 29. 7

"I'he lower end of rock arm 28 is curved out-- wardly and downwardly and carries a set screw 30 adapted to contact ywith the inner face of yoke 25. 0n the upper end of rock` arm 28 is pivotally mounted an outwardly extending link 31 as lby a pivot pin 32. On the outer end -of link 31 is secured in any convenient way (a new and improved way is disclosed in my copending application filed August 29, 1928, on shoe mounting for ironing machines, Serial No. 302,767) a shoe 33` provided with an internally located heating element 34.

rIhe front face of shoe 33 is curved to conform to'thecurvature of the roll 8 with which it is adapted to contact.

Just beneath pivot pin 32 and in rock arm 28 I provide a set screw 35 adapted to contact with the rear face of shoe 33 to prevent the same from moving downwardly about the pivotv 32 when the shoe with the roll 8. l

A leaf spring 36 here shown yas composed of four leaves of different lengths has its bottom end seated in the bottom of recess 26fand has its upper end in contact with the rear endof link 31.

In the bottom of'yoke 28is positioned a set screw 37 which is adaptedto be screwed inwardly against the `lower endof spring36 to cause the same to be forced against the shoulder 27.

The shoulder 27 functions as a fulcrum for the spring 36 so that the pressure of the upper end of spring 36 against the rear-end of link 31 may be increased by screwing inwardly 33 isout of contact the set screw 37 against the lower end of.

spring 36.

In order to vary the angular relation of be moved outwardly from yoke'25 which will cause the upper end of rock arm 28 to be moved in the opposite direction.

This outward movement of the upper end of rock arm 28 carrying link 31 will cause shoe 33 to be moved outwardly and away from roll 8. Conversely, if set screw 30 is screwed outwardly in the lower end of rock Varm 28, such lower end will be permitted to move towards yoke 25 carrying the upper end of rock arm 28 inwardly to move shoe 33 towards roll 8. f

When shoe 33 is out of contact with roll 8, the lower end of rock arm 28 carrying set screw 30 will be moved towards and held firmly lin contact with `yoke 28 due to the fact v that spring 36 will tend to move the upper end of rock arm 28 inwardly about the pivot I 29 and this vmovement will cause the lower end of rock arm 28 to be moved outwardly into contact withv yoke 25. i

The amount of pressure exerted by shoe 33 against roll 8 is determined by the' tension of spring 36 because of the fact that after shaft 20 is rotated in a manner hereafter to be de scribed to carry the shoe 33 into contact with the roll 8,'a slight additional movement of rotation of shaft 20, shoe 33 being in contact with roll 8, will cause rock arm 28 to be moved about its pivot 29 and this will cause set screw 2O to move out of yContact with yoke 28 so that the shoe 33 will be held under pressure contact with the roll 8 solely by the spring 36.

This position of parts is shown in Figure 12.

On lower rear face of casing 1 is provided a motor housing 38 in which is positioned an electric motor 39 indicatedin broken lines on Figure 8.

The armature shaft 40 -of the motor 39 is secured as by a coupling 41 to the end of the shaft 42. Shaft 42 has one end journaled in a.'

ball bearing 43 secured in casing 1 and has its opposite end journaled in a ball bearing 44 also secured in casing 1.

`Shaft 42 is provided with a worm 45.

Referring to Figure 6, a shaftI 46 is positioned in housing 1 in parallel relation to shafts 5 and 20 and has its outer end journaled in a ball bearing 47 secured in the outer end of casing 1 and has its inner end journaled in ball bearing 48 secured in the inner side of casing 1.

A spur gear 49 is rotatably mounted on shaft 46 and is provided with oppositely extending hubs, one of said hubs being journaled in a ball bearing 55. On the outer end of spur gear 49 is mounted a worm gear 50 secured to spur gear 49 as by a key 51. Worm gear 50 has an outwardly extending hub 52 between which and shaft 46'is interposed a ball bearing 53. A

On the inner hub of spur gear 49 is secured as by a key 53a clutch member 54l (see Figures 3, 6 and 11).

On the outer end of the inner hub of spur gear 49 is positioneda ball bearing 55.

A clutch and cam member 56 is rigidly fixed by press tit uponV shaft 46 and this shaft in y turn has its inner end located in a ball bearing 48 and its outer end in ball bearing 47 so that the clutch and cam member- 56 rotates on ball bearings-48 and 47 through the shaft 46 as a medium. The spur gear 49 rotates in ball bearing 55, Vwhich is housed in the clutch member 56, and in ball bearing 53 through the mediuml of the hub of the Worm gear 50, the worm gear 50. being rigidly secured by key 51 vupon .outer hub of spur gear 49. l

The outer end of member 56 has pivotally mounted thereon as by a pivotl pin 57 (Figure 3) a dog 58 adapted to engage slots 59 in clutch member 54. j

I )og 58 carries an inwardly extending pin 6() 1n engagement witha coil spring 61 (Figure 7) adapted to more dog 58 about its pivot 57 to bring it into engagement with a slot 59 in 'clutch member 54.

Adjacent the i'nner-faceof .dog 58 and pivotally mounted on pivot pin 57 is a plate 61 having an outwardly extending portion 62 in spaced ,relation to the end of dog 58. Such end of dog 58 is provided with an aperture 63 (Figure 5) in which is positioned coil i spring 64. A

A ball 65 isinterposed between the end of spring 64 and en d 62 of plate'61. A saddle shaped member 66 (Figure 11) has its lower end pivotally' mounted in casing l on pivot pins 67 and 68.

Member 66 is adapted to be moved about its pivots towards and from dog 58 to bring one of its upwardly extending and vopposed ends 69 or 70 into registration with the end 62 of plate 61. e lVhen one of the ends 69 or 70 is in the path of movement o'f dog 58 the dog 58 will be held upwardly out of contact with the clutch lmember 54.

Conversely when the member 66 if moved about its pivot to carry the ends 69 and 70 Nout of the path of movement of dog 58 such dog 58 will through spring 61 be moved about its pivot 57 lto bring it into engagement with the clutch member 54.

The member 56 has on its inner end a circular portion 71 eccentrically mounted in relation to the axis of shaft 46.

A ring 72 (Figure 7') encircles member 71 and is provided with a downwardly extending split yoke 73 through -Which extends a pivot pin 74.

A ball bearing 75 has its inner race mounted on pin 74 and has its outer race extending vthrough a slot in ring 72 into Contact with the periphery of member 71. Member 71 has a flattened portion shown at .-aon Figures 7 and 1() for -a purpose hereafter to be described.

A yoke 76 hasone end pivotally mounted' 011 the outer ends of pin 74 and has its other end pivotally mounted on a rock arm 77 (Figures 7 and 10) which is secured as by a key 78 and set screw 79 to shaft 20.

A latch 80 has its lower `end pivotally mounted in yoke 76 as by a pin 81 and has its upper end adapted to engage a shoulder 82 on arm 77.

To arm 77 is secured an upwardly extending link 83` to the upper end of which isseeured a coil spring 84. Coil spring 84 has its upper end secured as by a. pin 85 to casing 1 and is adapted to urge upwardly arm 77.

A shaft 86 (Figures 1 and 7) has one end journaled in the saddle 19 and has its other end journaled in casing 1.

Shaft 86 extends inwardly into casing 1VA and has secured on the end thereof a crank arm 87.

A link 88 connects the lower end of crank arm 87 and the upper end of latch 80 so 'that the rotaryniovement of shaft 86 will-cause the lower end of crank arm 87 to be moved in- 'end a knob For the purpose of limiting the upward wardly and this in turn through link 88'wi1l -cause latch 80 to be moved inwardly out of n registration with shoulder 82 on "crank arm movement of crank arm 77 I providein casing 1 a' stop 92 positioned in the path /fof movement of the crank arm 77.

d rIhe movement of the roll 8 is controlled by means of the following mechanism. (Figures 4, 6, 7 and 11).

. shoulder 94 and is secured in position on The inner end 93 of shaft 5 is reduced in size to form a shoulder 94. A spur gear 95 is rotatably mounted on the reduced end 93 of shaft with one face abutting against the shaft 5 by means of a nut 96. which is in threaded engagement with the end of shaft 5. The inner face of gear 95 carries a circular i-clutch member 97 having circumferentially lspaced jaws preferably tapered. A second clutch member 98 provided with. jaws preferably tapered adapted to engage clutch member 97 is slidably mounted on shaft 5 and is keyed thereto as by a key 99.

For the purpose of moving clutch member l98 into and out of contact with clutch member 97, I provided a Ueshaped shifting memj rear face of the jawed end 106 to move clutch i ber 100 having one of its lower ends pivotally mounted in casing 1 as by a pivot pin 101 and having its other end pivotally mounted in casing 1 as by a pivot pin 102.

One end of member 100 extends downwardly below the pivot 102 and is provided on its inner ,face with a rotatably mounted roller 103 for a purpose hereinafter to be described. y

On the upoerend of member 100 are provided opposed inwardly extending rollers v104 and 105 which rollers are positioned between the rear face of the jawed end 106 of clutch member 98 and an annular rim 107 formed on the rear end of clutch member 98.

The movement of member 100 about its pivots 101 and 102 will cause the rollers 104 and 105 to contact either with the rim 107 to move the .clutch member 98 out of registration with the clutch member 97 or with the member 98 into registration with clutch member 97.

A spiral spring 108 has one end encircling a post V109 secured in casing 1 and has the other end encircling a post 110 secured on clutch member 98 to normally urge such A spring 89 encircles shaft 86 and lnor-k .clutch member 98'towards and into regis'- tration with clutch member 97 For the purpose of moving member 100 about its pivot to disengage clutch member 98 from clutch member 97, I provide in housing 1 a rotatably mounted shaft 111 carrying on its inner end a cam member 112 adapted to contact with member 100 above the pivot 101 to move such member 100 about its pivot and into contact with rim 107 on clutch membe 98.

Onth other end of shaft 111 is provided a Alever 113 to provide a convenient means for manually rotating shaft 111. y

Lever 113 (Figures 14 and 15) carries a slidably mounted pin 114 normally spring pressed outwardly by a coil spring 1,15, the outward movement of pin 114 being limited by a transverse pin 116 carried adjacent the inner end of pin 114 and adapted to contact with lever 113.

In casing 1 is provided an aperture 117 .adapted to receive the inner end of pin 114 pwhen the same is in registration therewith and such pin 114 is pressed inwardly against the action of spring 115.

The relation of parts is such that when pin l 114 is in registration with aperture 117 cam member 112 will have moved member 100 about its pivot to carry clutch member 98 out of registration with clutch member 97.

Spring 108 will continue to exert pressure against member 100 and therefore against cam 112 and will therefore cause shaft 111 to be rotated to carry lever 113 to its normal position whenever the pin 114 is moved outwardly from aperture 117.

The pressure exerted by spring 108 on the parts just described will cause pin 114 to be held in aperture 117 by friction against the pressure of spring 115 which is a comparatively light spring as compared to spring 108.

When pin 114 is in aperture 117 and it is desired to return the parts to the normal position, it is only necessary to touch the end of leverl 113 with sufficient force to relieve pin 114 from any tension from spring 108 for when this is done the pin 114 will be moved outwardly from aperture 117 by means of spring 115 and when lever 113 is thus released it will be returned to its normal posi tion through the action of spring 108.

Y In Figure 15 I have shown in heavy lines the relation of parts when pin 114 is positioned in aperture 117 and I have indicated in dotted lines the position of pin 114 when the same has been allowed to move outwardly out of registration;` with aperture 117.

means whereby member 100 may be moved about its pivot to move clutch member 98 out of registration with clutch member 97 I provide on member 56 an outwardly extending lug 118 having a cam surface 119 adapted, when member 56 is rotated, to contact with For the purpose of providing an automatic l l1,825,350 p l I 5 roller 163 carried on member 100 to force the lower end of member 100 forwardly to move such member 100 about its pivot, which movement will'cause clutch member 98 to be carried out of engagement with clutch member 97.

For the purpose of controlling the movement of the member 66 which itself controls the operation `of the clutch composed ot' members 54 and 58,l I provide a dual means, one manually `controlled and the other electrically controlled.. 1

The manual control comprises a shaft 12`0 rotatably mounted in casing 1 on the outside end of which I provide a lever 121 topermit eas manual manipulation thereof.

n the inner end of shaft 120-and`secured thereto as by a pin 122, I provide a member 123 having a downwardlyextending arm 124 adapted to contact with member 66 above its pivot 68. The bottom end of arm 124 is bent outwardly and forwardly and is adapted to contact with a set screw 124 carried on thej side offa'V boss 68 on casing 1 to-limit the movement of member 123 about its pivot in one direction.

AOn the other end of member 123, I provide an upwardly extending member 125 having an offset arm adapted tocontact with a set screw 125 carried on the side of a boss 101 on casing 1 to limit the movement ofmember 123 about its pivot in the other direction.

A spring 126 encircles shaft 120 having its upper endv abutting against the offset end of arm 125 and having" its lower end engaged with a hook-like member 127 which extends laterally from a depending leg 128 on member 66.

The disposition of spring 126 is such that it tends to hold the bottom end of member 66 outwardly and the upper portions thereof 69 and 70 in the pathy of movement of the dogr 58. This movement of member 66 is limited due to the fact that member 66 will contact with arm 124 which is heldl against movement by set screw 124.

Vhen the lever 121 is moved downwardly to rotate shaft 120 the lower end of the arm 124 on member 23 will bear against member 66 to carry the upper portion thereof out'- Wardly and to move the parts 69 and 70 of y said member`66 away from the path-of movement of dog 58. This movement of parts is limited because of the fact that member 125 will contact with set-screw 125.

The construction just described can'.- best be seen from Figures 9 and 11 as can the construction of the electrical control about to be described. l

The electrical control for the parts just described comprises an electro-magnet 129 having an armature 130 pivotally mounted on the frame thereof. Qn the lower end of armature 130 is provided a clip 131 adapted to engage the lower portion 128 of member 66.

It will be obvious that when the magnet 129, is magnetized the armature 130 willbe Y moved towards the magnet 129 carrying with it lower end 128 of member 66 which When the magnet 129 is demagnetized the spring 126 will cause the member 66 to return to the normal position. I have not here shown a switch for controlling the magnet 129 but I prefer to use a foot operated switch connected to a lead so that the operator may actuate this part (fif the mechanism and stillhave both hands ree.

The relation of parts is such that when the yoke 76 is in the lowered position the arm 77 will also be in the lowered position and the shoe 33 will be in pressure contact with the roll 8.

Vith the parts in this position7 the flat portion -aof the cam member 71 will be in the bottom position and will be in opposed relation to the ball bearing 75 so that the thrust from the shoe 33 through the various parts which connect it to the ring 72 will be carried solely by such ring and not to any degree by the ball bearing 75.

Assuming that the parts just described are in the position shown in heavy lines on Figure 10 and the shaft 90 is manipulated,

to release the latch 80 from the shoulder 82 on arm 77, the spring 84 through the link 83 will carry the arm 77 upwardly to the position shown in dotted lines on Figure 10 and this in turn will carry the shoe 33 outwardly from the roll 8 to the position also indicated in dotted lines on Figure 1U.`

If the clutch members 54and 58 are then permitted to come into engagement to cause the rotation of member 56, the inner end of yoke 76 will be carried upwardly by the movement of the cani until the latch 8U is raised to the shoulder 82 on member 77 l and into the position shown in dotted lines on Figure l0. When latch 80 reaches this latter position it will be pulled outwardly by the action of spring 89 into engagement with the shoulder 82 so that the actuating parts for the shoe 33 will be again locked together in the normal operating position.

lVhen the ring 72 is in the lowermost position and the shoe 33 is in pressure contact ber 56 will be out of engagement with the roller 103 carried on member 100.

When, however, cam 7 2 is further rotated to raise the yoke 76 to the highermost position, which movement will cause the shoe 33 to be moved away from the roll 8, the cam surface 119 will Contact with the roll 103 to cause the member 100 to be moved about its pivots against the action of spring 108 to move out of engagement the clutch members 106 and 97 and therefore permit the roll 8 to come to rest. If, for example, it is 'desired to ironor press material such as, for example, a pair oftrousers, it is preferable to move the shoe 33 into and out of contact with the roll 8 while the latter is at rest.

When it is desired to operate the ironer under these conditions, the operator moves the lever 113 downwardly and pushes the pin 114 into engagement with the aperture 117. This movement of lever\113 will cause the `cam 112 on thevshaft 111 to bear against the mits it to be returned to the normal position through the action of spring 108.

For the purpose of insuring a complete disengagement of clutch member 58 from clutch member 54 so that there may be no possibility of the two touching when in the disengagedl positiony with resulting noise and vibration, I have provided the plate. 61 shown on Figure 5. j

When the member 66 is out kof the path of movement of the clutch member 58 and such clutch member 58 is in engagement with clutch member 54 and it is then desired to separate clutch members 58 and 54, the member 66 in the manner heretofore described is moved about its pivots so that either the portion 69 or the portion 70 of member 66 will be moved into the path of movement of clutch member 58.

The portion 62 on plate'61 will then be brought into contact with, for example, the portion 69 on member 66. The dog 58 will continue its movement against the action `of spring 64 until the dog 58 contacts with the portion 62.

The portion 62 being held against movement by the portion 69, the further movement of dog 58 will be interrupted so that the continued rotation of clutch member 54 will cause dog 58 to be moved about its pivot 57 and out of engagement with the slot 59 in which it was positioned. When dog 58 iS freed from clutch member 54 the spring 64 will cause dog 58 to be moved upwardly a further distance so that it will be in spaced relation with member 54.

For the purpose of limitin the movement of plate 61 about its pivot 5 I provide on the end of plate 61, an offset arm 62 adapted to contact with a shoulder 63 on member 56.

may be connected to any convenient lsource of potential.

It will also be understood that `a switch is provided for connecting the heating element 34 to the circuit which is connected to the source of potential.

,n The ironing machine here disclosed is particularly well adapted to be used in ironing or pressing different types of materials because of the fact that it may be operated in a number ofdiiferent ways depending upon the material which it is desired to subject to the operation of the machine.

For example, the roll 8 may be permitted to rotate continuously while shoe 33 isy in pressure contact therewith or the roll 8 may be left at rest while the shoe 33 is moved'in'to and out of pressure contact with such roll. Or, if desired, during the ironing operation the shoe 33 may be caused t'o be moved out of pressure contact with the roll 8 and the roll 8 allowedl to come lto rest to permit thev arrangement of clothes on the roll.'

Furthermore, l provide a manual means for moving the shoe 33 out of contact with the roll 8 irrespective of the other mechanism of the machine.

This latter means is provided so that clothes positioned between the shoe 33 and the roll 8 may be removed therefrom even if the machine should be stopped, throughrv the blowing of a fuse or from some other cause, while the heated shoe 33 was in pressure contact with the roll 8. ,t

If the shoe 33 has `been manually moved away from the roll 8 and the machine then resumes its operation the shoe 33 will, as above described, be automatically reconnected to the operating mechanism without any action on the part of the operator.

Referring to Figures 1 and 16, the outer end of shoe 33 has the rear side curved inwardly and outwardly as shown at 33. This construction is a decided improvement over any ironing shoes known to the art in that it permits the operator to retain hold of the article to be ironed up to the point where it passes underneath the shoe without any liability of the hand of the operator coming into contact with the heated shoe. vSuch action on the part of the operator is essential s y when certain articles such as ruflles or col- .self to the exact size, shape or relation of parts as various changes may be made with-v in the scope of the appended claims.
